Developers are trying to keep selling offsets from hundreds of controversial projects through a revamped United Nations mechanism, sparking fears that worthless credits will allow companies and countries to pollute.
Climate Home analysis shows that renewable energy investments make up four-fifths of all projects seeking a transfer from the old Clean Development Mechanism (CDM) to the new system under article 6.4 of the Paris Agreement.
Experts have long written off the vast majority of credits produced from renewable energy as junk because they often already provide the cheapest sources of power in most of the world and selling offsets to fund them does not have any additional impact on emissions.
Some of these projects have also been accused of human rights violations such as forced evictions for the construction of large dams.
Harry Fearnehough from New Climate Institute told Climate Home that “it could definitely undermine the credibility of the mechanism because, while there’s still uncertainty over what it will look like, as a starting point you have a huge supply of low-quality offsets that are potentially available at a very low cost”.
Established in 1997 by the Kyoto Protocol, the UN’s CDM allowed rich countries to meet some of their climate obligations by financing emission-cutting projects in poorer ones.
The programme has received widespread criticism for its patchy human rights record and for failing to deliver promised climate benefits. Supporters of a new mechanism currently being developed under article 6.4 of the Paris Agreement say it is an improved, higher-integrity successor to the CDM.
Winning a lifeline
Countries are still wrangling over many aspects of the future market, but one much-debated issue was settled at Cop26 in Glasgow.
Under pressure from Brazil, Russia, China and India, countries agreed that a vast number of projects originally created under the CDM were allowed to migrate to the new mechanism. This handed them the chance to significantly extend their lifespan and their potential credit sales.
Project developers had until the end of December 2023 to fill in a simple two-page form and submit their transition requests.

Of the nearly 3,500 eligible projects, over a third (1,284) seized that opportunity.
In total, the projects that have requested transition by the deadline could supply 700 million tons of carbon credits between 2021 – the start year for accounting purposes set by the regulation – and 2035, according to a preliminary analysis by NewClimate Institute shared with Climate Home. That is more than the annual CO2 emissions of Germany.
While a relatively small share of the projects opted in, they account for approximately three-quarters of the potential supply of carbon offsets.
That’s because some of the programmes seeking to move could produce an outsized volume of credits. The two biggest ones – a hydro plant and a nitrous oxide emission reduction scheme, both in Brazil – each have the potential to issue around 6 million tons of offsets a year. That’s similar to the annual emissions of Sierra Leone.
Fearnehough says that “very few, if any, of these credits are genuinely likely to be additional”, going beyond what countries would do anyway without the carbon finance.
“A key reason for this is that the CDM was really only scheduled to run up to the end of 2020,” he added. “No investor would have made a decision purely based on expecting revenues from credits in the 2020s because, quite simply, there was no political indication that the possibility to move over to a new mechanism would exist”.
Climate and social concerns
That is particularly true for the renewable energy projects vastly dominating the list. Experts say they are highly likely to fail the additionality test, meaning their credits do not bring any climate benefit. When used to compensate for real emissions elsewhere, they result in more greenhouse gases entering the atmosphere.
The reason is simple. Many renewable offsets came into existence just as solar and wind power were becoming the cheapest source of energy in most countries. After years in operation, they are likely to be profitable from the sale of the electricity alone, without the need for additional revenues from carbon offsetting.
A 2016 study commissioned by the European Commission concluded that the vast majority of these projects “are not providing real, measurable and additional emission reductions”.

Hydropower projects carry even more concerns as their implementation is often marred by human rights problems. Vulnerable communities relying on rivers for their livelihoods are particularly at risk of forced displacement.
The largest project applying for the transition to the new mechanism – the Jirau mega-plant in Brazil’s Rondonia state – is a case in point.
Over the years the project has faced multiple accusations of stoking tensions, pushing indigenous people away from their territories and breaching the rights of the workers that built it. Engie, the project’s developer, previously rejected any accusations.
Other categories of activities featuring prominently on the transition list have raised major concerns in the past.
Credits from projects which claim to cut or stop the emission of industrial gases such as nitrous oxide (N20) and trifluoromethane (HFC-23) were banned by the EU in 2013 for use in its emission trading system.
That’s because, according to studies, they created “a perverse incentive” to increase the production of gases depleting the ozone layer.
Countries’ authorisation dilemma
While the CDM projects have now made their move and requested transition, they are not automatically through to the new system.
Standing in their way is the need to receive a formal authorisation to proceed from the countries where their activities are located. Governments have until 2025 to make a decision and, experts predict, it won’t be a straightforward one.

“It’s not a guarantee that all host countries will want to approve all of these projects”, according to Jonathan Crook from Carbon Market Watch, who said there would be contrasting forces at play.
“If they authorise them, they have to do corresponding adjustments, which they might not be so keen on since those emission reductions will be deducted from their [NDC climate plans]. But, at the same time, most projects are located in very large countries and it may not make a big difference to their plans”.
The answer to this dilemma will rest primarily in the hands of China, India and Brazil. Between them, the countries host around three-quarters of all projects that are looking to migrate under article 6.4.
Spotlight on three countries
Observers of climate talks said their governments all pushed for rules that would grant a lifeline to as many CDM projects as possible when those negotiations took place at Cop25 in Madrid and Cop26 in Glasgow. But, since then, they have been conspicuously quiet on the topic.
Climate Home approached the respective carbon market authorities in the three countries but did not receive a response at the time of publication.
Trishant Dev is a carbon market expert at the Delhi-based Centre for Science and Environment. He expects there will be “a lot of pressure on the Indian government to let projects through from the carbon industry, which is thriving in the country”.
But, at the same time, he thinks the government will take time to properly understand all the pros and cons of allowing such authorisations. “It’s a chaotic process. Countries want to make sense of what the final outcome of the article 6 discussions will be and how that will interact with domestic carbon markets they are constructing”, he said.
Who will buy the credits?
Article 6 talks collapsed at Cop28 last December after attempts led by the EU to introduce tighter controls and further integrity safeguards had been rebuffed by the US. Negotiators will try again this year to hammer out a deal on many technical issues that need to be resolved before trading of offsets can begin.
Meanwhile, questions also remain on who will be interested in using those credits, once the market is up and running. Countries, corporations and individuals could all be potential buyers.
New Climate Institute’s Fearnehough said there doesn’t seem to be much appetite from countries based on what they are saying in public. “But it’s hard to predict what will happen when suddenly the offsets are available and you have an easy option to meet your NDC targets”, he added.
The credits may gain more interest from polluting companies. Banks, airlines and industrial heavyweights keep buying large volumes of questionable renewable energy offsets despite the known concerns, a Bloomberg investigation found. Dressing them up with the UN stamp of approval may add to the appeal.
Carbon Market Watch’s Crook believes much will depend on the transparency of the system – something still largely unknown. “If there is a very transparent register disclosing who purchased how many credits and for what purpose, that would disincentivize companies from transacting low-quality credits out of reputational fears,” he said. “But if it isn’t transparent, buyers may not be as careful with due diligence or may be even encouraged to buy bad credits since there won’t be scrutiny”.

An older teaching about land acknowledgement
As I have come to understand the spirit and intention of land acknowledgement, I often return to fond memories of my grandmother and her words of wisdom. She taught that the health of the places we call home comes first, because the wellbeing of the people depends on it.
In her teaching, land acknowledgement began with the land. Long before it became a paragraph read at the start of a meeting, it was a way of recognizing a homeland: its waters, its species, its seasons, and the spirit that revealed whether the place was well.
Her teaching echoes a practice found across many Indigenous Nations. Haudenosaunee gatherings, for example, have long opened with the Ohén:ton Karihwatéhkwen, the Thanksgiving Address, often translated as “the words that come before all else.” The speaker greets and gives thanks to the people, the earth, the waters, the plants, the animals, the winds, the sun, the moon and the stars. Only after everything that sustains life has been acknowledged does the gathering turn to its own business.
That order changes what an acknowledgement is for. Its purpose was to share the story of a place with neighbours and to draw them into the work of tending it. People entered the story second, as the ones responsible for what had just been named.
Understood this way, an acknowledgement does more than open a meeting. It asks us to reconsider where we stand, and what we owe the ground beneath us.
Nations among nations
In her teaching, people are one nation among many. The salmon are a nation. So are the cedars, the bison, the medicine plants, and the pollinators. Each belongs to a place, carries its own responsibilities, and offers gifts no other nation can give.
This idea of kinship runs through many Indigenous philosophies. The phrase “all my relations,” heard in ceremonies and gatherings across Turtle Island, is a reminder that family extends beyond people to the animals, plants, waters and lands that make life possible. Some Indigenous languages carry the same understanding in their grammar, speaking of many plants, animals and natural forces as living beings rather than objects.
Sovereignty, understood through this relationship, is a kind of standing more than a form of control. Each nation belongs fully to its place and carries its share of that place’s life. No nation thrives alone, and none thrives by taking over the whole.
The land is also the source of instruction. Over generations, people watched how a river valley or a stretch of prairie kept itself well: who arrived when, who fed whom, and how much could be taken before the giving stopped. In my grandmother’s telling, those observations became instructions, and those instructions helped shape law and protocol. They guided when to harvest, where to camp, how to enter a neighbour’s territory, and what was owed in return.
Indigenous legal scholars today often describe this as law that comes from the land itself, learned by watching how living systems sustain one another. A plainer name for it is knowing how to live somewhere.
The host and the guest
One of the clearest teachings in this understanding of the world is the relationship between host and guest. My grandmother invited us to recognize that relationship in the lives of plants and animals.
A host prepares the place before anyone arrives. A beaver family dams a stream, and the pond becomes a home for fish, frogs, birds and plants. A fallen tree becomes a nurse log, feeding the next generation of seedlings as it returns to the soil.
A host offers first. A flowering plant sets out nectar. A berry bush ripens fruit. These provisions come in their own season, not whenever a visitor happens to want them.
A host also makes its presence known. Birdsong, scent and the marks left along a trail tell newcomers that a place is already inhabited. The visitor does not arrive in an empty world.
The guest has responsibilities too. A guest attends to the season and to what the place can offer. A guest does not assume that everything within reach is theirs to take. A guest leaves something that helps sustain the relationship.
A bee takes nectar and carries pollen. Read through this teaching, that exchange offers an image of visiting well: receiving a gift while helping the host continue its life.
Many Indigenous harvesting protocols carry the same ethic into daily practice: ask before taking, take only what is needed, offer thanks, and leave enough for others and for the plant or animal to recover.
None of this suggests that every relationship in nature is peaceful or generous. These are ways of seeing responsibilities that people can learn to carry.
Everyone is both
No being is only a host or only a guest.
A tree makes room for other life while depending on soil, water, sunlight, fungi, and relationships beyond itself. People, too, may welcome others into their homes while remaining dependent on the larger homeland that sustains them.
The distinction between host and guest is therefore about roles, not ranks. Everyone receives. Everyone has something to give.
The question is whether the exchange sustains the place.
A visitor who takes without restraint leaves less for those who come next. A host who neglects the place has less to offer. Both have responsibilities, and neither can fulfil them alone.
This is the heart of reciprocity, a principle found across Indigenous philosophies: relationships stay healthy when gifts move in both directions. The Haudenosaunee teaching of the seventh generation extends that exchange across time, asking that decisions made today leave the place well for those not yet born.
Mutual benefit begins here, with the recognition that different beings carry different gifts and obligations.
What people carry forward
My grandmother’s teaching connects these relationships to the ways people meet their neighbours.
The host prepares a place, offers food and rest, and explains where the visitor has arrived. The guest makes themselves known, explains why they have come, listens to the terms of the visit, and brings something in return. The gift may be material. It may also be labour, knowledge, news, or a commitment to help.
Nations around the Great Lakes carried this ethic into treaty. The Dish with One Spoon, an agreement among the Haudenosaunee, Anishinaabe and allied Nations, describes shared hunting grounds as a single dish. Everyone eats from it with one spoon, takes only what they need, leaves enough for others, and keeps the dish clean. The Two Row Wampum, between the Haudenosaunee and European newcomers, shows two vessels travelling side by side on the same river, each keeping its own ways and neither steering the other.
In this understanding, acknowledgement is more than naming the people associated with a territory. It is learning enough about a homeland to behave responsibly within it.
Whose home is this? What sustains it? What laws and agreements guide our presence? What can we receive, and what must we return?
These questions make acknowledgement a relationship rather than a recital.
They also make it diplomatic. A guest who recognizes the host’s homeland recognizes that they have entered a place with its own relationships and responsibilities. A host who welcomes the guest makes room for an encounter governed by those relationships.
Neither arrives without standing. Neither arrives without obligations.
Beginning with place
I write from the shores of the Bay of Quinte. Here, the teaching asks me to begin with the water, the shoreline, and the life they sustain. Before I describe myself, I must attend to where I am.
That does not make people or history less important. It places them within the homeland that gives them meaning. The people, their laws, their agreements, and their responsibilities all belong to the place.
In a time of longer fire seasons, troubled waters, and uncertainty about what the next season will bring, this teaching asks something difficult and useful of us: pay attention before you speak.
An acknowledgement cannot tell the story of a place if the speaker has stopped noticing it.
The land came first. Beginning there again means learning to name what sustains us, and accepting that what sustains us also asks something of us.

Carbon dioxide (CO2) emissions from fossil fuels and cement are projected to fall by around 0.4% in 2026 to 38.2bn tonnes of CO2 (GtCO2), according to new figures from the Global Carbon Project.
This guest post is by:
- Dr Zeke Hausfather, Carbon Brief’s climate science contributor
- Prof Pierre Friedlingstein, chair of mathematical modelling of climate systems at the University of Exeter and part of the Global Carbon Project team.
Carbon dioxide (CO2) emissions from fossil fuels and cement are projected to fall by around 0.4% in 2026 to 38.2bn tonnes of CO2 (GtCO2), according to new figures from the Global Carbon Project.
The 21st edition of the annual “global carbon budget” report, published today, says that this small decline is largely due to a 1.9% drop in emissions from oil and the energy shock triggered by the Iran conflict and the closure of the strait of Hormuz.
Emissions from coal continue to increase slightly.
The Global Carbon Project’s projections for fossil fuel and cement CO2 emissions in 2026 are preliminary, with a range that spans a fall of -1.5% to a rise of +0.6%.
This means a small increase in emissions can not be ruled out.
Emissions from land-use change, such as deforestation, are projected to rise in 2026.
This is primarily driven by peat fires and forest degradation in south-east Asia and is linked to the development of a strong El Niño event this year.
As a result, total CO2 emissions from fossil fuels and land use are projected to reach a record high of 43.3GtCO2 in 2026 – marginally above 42.8GtCO2 in 2025.
Research published alongside the report by the same team in Nature Climate Change finds that the growth in solar, wind and electric vehicles (EVs) now offsets around two-thirds of the emissions that would otherwise come from rising energy demand.
However, the deployment of these technologies is not yet enough to push global emissions into a sustained decline, according to the study.
The 2026 global carbon budget report also estimates that:
- Fossil emissions are projected to fall in China (-0.9%), the US (-1.3%) and the EU (-1.5%) in 2026, but rise by 4.4% in India.
- Oil emissions are projected to fall in every major region, with the largest drop in China (-4.6%).
- Land-use emissions averaged 4.9GtCO2 per year over 2016-25, around 21% lower than the decade before.
- Total CO2 emissions (fossil and land-use) grew by an average 0.3% per year over the past decade (2016-25), compared with 1.7% per year over the decade before.
- The remaining carbon budget to limit warming to 1.5C is 150GtCO2, or less than four years of current emissions.
- The land sink in 2025 was the highest on record, rebounding after being weakened during the 2023-24 El Niño. The current El Niño is expected to weaken the land sink in 2027.
- The concentration of CO2 in the atmosphere is set to reach 427.7 parts per million (ppm) in 2026, 54% above pre-industrial levels.
(For more on previous editions of the Global Carbon Project’s annual report, see Carbon Brief’s coverage in 2025, 2024, 2023 and 2022.)
Total emissions edge up as land-use emissions rise
Total global CO2 emissions, which combines fossil fuels and land-use change, are projected to reach a record high of 43.3GtCO2 in 2026, up from 42.8GtCO2 in 2025.
The increase in 2026 comes entirely from a projected rise in land-use emissions, which are more challenging to estimate than fossil emissions.
(The global carbon budget groups emissions from fossil fuels and cement production as “fossil emissions”. Carbon Brief follows this convention throughout this piece.)
If land-use emissions had stayed at 2025 levels, total emissions would have fallen slightly in 2026 to around 42.6GtCO2.
Each edition of the global carbon budget updates the historical record as new data and methods become available. The chart below shows total emissions in this year’s budget compared with the five previous editions.
This year’s estimates of historical fossil emissions are around 0.3GtCO2 per year higher than in last year’s budget.
This is largely because the report now estimates a smaller “cement carbonation” sink in the wake of research published this year in Communications Sustainability. In other words, it estimates that cement is able to slowly reabsorb less CO2 over its lifetime than previously thought.
Estimates of land-use emissions have also been revised, including a spike in 2018 – visible in the chart above – linked to updated cropland data for Colombia.
The updated numbers show that total emissions have grown by 0.3% per year over the past decade (2016-25), compared with 1.7% per year over 2006-15.
Fossil emissions grew about 0.9% per year in the past decade, compared with 1.9% the decade before. Over the same period, land-use emissions have declined.
While the slowdown reflects real progress, a plateau in emissions is still a long way from the rapid declines needed to reach net-zero emissions and stabilise global temperatures.
With human-caused warming reaching 1.37C above pre-industrial levels (1850-1900) in 2025, the report estimates that the remaining carbon budget to limit warming to 1.5C, with a 50% chance, is 150GtCO2 from the start of 2027. That is less than four years of 2026 emissions.
Meanwhile, the budgets for 1.7C and 2C are 510GtCO2 and 1,035GtCO2, respectively – or around 12 and 24 years of current emissions.
Fossil emissions made up around 88% of total CO2 emissions over the past decade, with land-use change making up the remaining 12%.
This is a marked change from the first half of the 20th century, when land-use emissions were larger than those from fossil fuels.
The figure below shows global emissions, split into fossil and land-use components.
